One of the great problems as discerned by pilots was the tendency for the carburetted engine to cut out under negative 'G'. Luftwaffe pilots learned to escape by simply pushing the nose of their aircraft down into a dive, as their fuel- injected engines did not cut out under these circumstances.
By 1941 Miss Tilly Shilling in Farnborough had developed a partial cure for the problem. A diaphragm across the float chambers with a calibrated hole (the infamous Miss Shilling's orifice)
hock: allowed negative 'g' manoeuvres, and was fitted as standard from March 1941. Sustained zero 'g' manoeuvres were not sorted out until somewhat later. In 1942 an anti-g version of the SU carburettor was fitted to single and two-stage Merlins.
In this game our Mk.VB uses correctly the last one. :wink:
